Abstract

A circuit board for body fluid collection includes a circuit board portion including an insulating layer and a conductor pattern which is supported by the insulating layer and in which an electrode, a terminal to be connected to a device for measuring the component of a body fluid, and a wire which electrically connects the electrode and the terminal are integrally provided. The circuit board for body fluid collection comprises a puncture needle for extracting the body fluid by performing puncturing, which is formed integrally with the circuit board portion and which is protruded from the circuit board portion, and a guard portion for guarding the tip of the puncture needle, which is arranged in opposition to the puncture needle in the lower flow side in the puncture direction of the puncture needle.

Claims

1. A circuit board for body fluid collection comprising:

a circuit board portion including an insulating layer, and a conductive pattern supported on the insulating layer and integrally including an electrode, a terminal for connecting to a device for measuring a component of a body fluid, and a wire electrically connecting the electrode and the terminal;

a puncture needle integrally formed with the circuit board portion, and protruding from the circuit board portion in order to collect the body fluid by puncture; and

a guard portion disposed downstream of the puncture needle in a puncture direction in opposing relation thereto in order to guard a tip of the puncture needle.

2. The circuit board for body fluid collection according to claim 1, further comprising:

a releasing portion for releasing the guarding of the tip of the puncture needle by the guard portion, by bringing the guard portion and the puncture needle away from each other.

3. The circuit board for body fluid collection according to claim 2, wherein

the guard portion is supported by the circuit board portion, and

the releasing portion is bendably provided in a portion of the guard portion located upstream of the tip of the puncture needle in the puncture direction.

4. The circuit board for body fluid collection according to claim 2, wherein the releasing portion is bendably provided in a portion of the puncture needle or the circuit board portion located upstream of the tip of the puncture needle in the puncture direction.
